PUMP.

SPECIFICATION forming part of Letters Patent No. 792,081, dated J' une 13, 1905.

Application filed August 17, 1904. Serial No. 221,067.

To all whom itv may concern:

Be it known that I, JAMES MILLER SHEP- ARD, a citizen of the United States, residing at Findlay, in the county of Hancock and State of Ohio, have invented a new and useful Pump, of which the following is a specification.

This invention relates to improvements in that class of pumps wherein fluids such as conipressedair, gas, or the like are employed asav'direct agent for effecting the elevation of liquids.

The prime object is to provide mechanism of a simple nature that will bring the air or driving fluid into coaction with the water or liquid to be elevated, so that the force of the former will be very effectively utilized on the latter, a continuous flow of the li uid being secured with a comparatively smal expenditure of force, the submergence being comparatively slight, and the construction being such that should the occasion arise the pump complete can ybe readily removed and replaced without the necessity of pulling the well tubing or casing.

In the accompanying drawings, Figure 1 is a side elevation of a well with the improved pump structure therein. Fig. 2 is a longitudinal sectional view, on an enlarged scale, through the lower portion of said well. Fig. 3 is a cross-sectional view, on an enlarged scale, on the line 3 3 of Fig. 2. Fig. 4 is a similar view on the line 4 4 of Fig. 2. Fig. 5 is a view in elevation of the pump-body. Fig. 6 is a sectional view, on an enlarged scale, through the head. Fig. 7 is a side elevation of a slightly-modified form ol head, and Fig. 8 is a top plan view thereof.

Similar reference-numerals indicate corre- .sponding parts in all the iigures of the drawings.

In the embodiment illustrated in the first six iigures a barrel 9 is employed, having at its lower end an inlet-strainer 10, connected to the lower end of said barrel by a coupling 11, having a bore 12 therethrough and a tapering seat 13 in the upper end. A standing valve member is employed comprising a plug 14, the lower end of which is tapered and adapted to fit snugly in the seat 13, said plug carrying 'a depending tube-section 15, that extends downwardly through the bore 12 of the coupling 11, and preferably into .the strainer 10. The plug 14 is threaded into the lower end of a tubular casing 16, and s up- 5 5 ported on the upper end of said plug is a valve-cage 17, located within the tubular casing 16 and containing a ball-valve* 18, coperating with a seat 19, held within the cage upon the upper end of the plug. The said 6o cage is maintained in place by means of an annular shoulder 20, formed within the lower portion of the tubular casing 16 and bearing upon a shoulder formed on the cage, the lower portion of said cage thus being clamped between the shoulder 2O and the upper end of the plug 14, all of which will be apparent by reference to Fig. 2. The casing 16 forms a liquidchamber 21, the inlet to which is controlled by the valve 18. The upper end of this chamber 7o is defined by a head 22, the lower portion of which is threaded into the upper end of the tubular casing, said head also iittmg snugly within the barrel. Liquid-discharge openings 23 extend upwardly through thehead 22, coin- 7 5 municating with the chamber 21 at their lower ends and at their upper ends communicating with upwardly-extending nozzles 24 in the form of tubes, that are preferably threaded into the upper end of the head and 8o may be inclined inwardly, as shown. The openings 23 are arranged in an annular series about a central bore 25 in the head, the upper and lower portions of said bore being threaded. A tube 26 is screwed into the 8 5 lower end oi the bore and depends within the liquid-chamber 21. vThe lower end .of this tube is closed by a plug 27, and said tube forms a fluid-chamber 28. A fluid-supply pipe 29 extends longitudinally within the 9o barrel and is screwed into the upper 'end of the bore 25, said pipe thus communicating with the fluid-chainber. The pipe extends to the top of the well, where the tubing is provided with a suitable offset coupling 30, having an upstanding nozzle 31, through which the pipe projects, as shown in Fig. 1, said pipe leading from any suitable source of fluid under pressure. The head 22 is furth\ei"i'riore provided with an annular series of 100 fluid-outlet openings 32, communicating at their lower ends with the fluid-chamber and terminating at their upper ends in dischargeorifices, one of these orifices being preferably located between each pair of nozzles 24, as shown in Fig. 3, but being disposed below the discharge ends of said nozzles, as will be apparent by reference to Fig. 2.

The operation of the pump may be briefly described as follows: Air or other suitable fluid under pressure admitted through the pipe 29 will pass downwardly into the chamber 28 and escape through the outlets 32 longitudinally of the nozzles. Passing the ends of said nozzles with considerable force avacuum will be formed therein, which will be supplied with liquid drawn through the lower valved inlet of the liquid-chamber 21 and thence in jected or j etted upward through said nozzles into tubing. The force of the discharging fluid is sufficient to elevate the liquid continuously ejected from the nozzles above the outlets 32, so that a continuous stream is discharged from the well, and the peculiar dispositoin of the nozzles and air and fluid outlets secures an effective operation of the pump and a thorough utilization of the force of the fluid employed for elevatmg the liquid. Moreover, in this structure no back pressure can take place, as the only discharge of the elevating fluid .is in an upward direction, and there are no joints in the fiuidsupplying means which cannot be made fluid-tight to prevent the escape of the ejecting means in the wrong direction. It will, furthermore, be observed that the head is secured to the supply-pipe and that the standing valve member is connected to said head by the tubular casing 1.6. Therefore if it becomes desirable or necessary to remove the pump all that is required is to elevate the supply-pipev29, whereupon the pump in its entirety is carried upwardly, and thus removed without the necessity of pulling the well-tubing.

It is to be understood that the invention is not limited to the specific details shown and described above, but that various changes in the shape, size, proportions, and minor details of construction may be made. As an example of this, attention is invited to Figs. 7 and 8, where a slightly-modified form of head is illustrated. The fluid-feed pipe` is shown at 29lrL and is secured in the usual manner to the head 30, said head carrying the depending tube 31a, forming an air-chamber. The liquid-discharge nozzles 32a are arranged about the pipe 2Q" and have their intermediate portions inset, as shown at 33a, their upper ends exten ding in a substantially vertical direction. At this point it is desired to state that the nozzles may be changed as to size, number, and disposition without in any manner departingfrom the spirit of the invention. The fluid-discharge orifices 34C are also arranged about the supply-pipe 29a, and in this construction one of said orifices is located in the space between the adjacent nozzles.

Having thus described my invention, what I claim as new, and desire to secure byLetters Patent, is-
